ASSIGNORS, BY MESNE ASSIGNMENTS, TO NINETEEN HUNDRED CORPORATION, OF BINGHAMTON, NEW YORK, A CORPORATION OF NEW YORK ICE-GBEAM-FREEZING ATTACHMENT FOB WASHING MACHINES Application filed October 14, 1927. Serial No. 226,107.

Our invention relates to a power driven ice cream freezer, more particularly to an ice cream freezing attachment for a household washing machine, and has for its ob ect the provision of apparatus of the character desaignated which shall be simple of construction and which shall be readily applied to, or detached from the washing machine.

A more specific object of our invention 1s to provide means for supporting the stationary parts of an ice cream freezer from the stationary parts of a washing machine, and

to provide a novel coupling and power transmitting means from the movable parts of the washing machine to the movable parts of the ice cream freezer.

A further object of our invention is to provide an ice cream freezing attachment for a washing machine wherein the brine tank of the, freezer is provided with means preventing leaka e of brine into the tub of the washing machlne.

I Our invention is adapted for attachment to a number of well known, commonly used household washing machines. The type of washing machines to which it is particularly adaptable is one having a stationary tub with rotatable agitating means within the bottom of the tub. Our ice 'cream freezer has the same general features found inpractically all apparatus of that type, coupled with novel means to adapt it for the purposes described and "novel supporting means for connecting it to the washing machine. Preferably, the stationary parts of the ice cream freezer are connected to the stationary tub of the washing machine and are concentrically arranged with respect to the axis of rotation of the agitator. The rotatable parts of the ice cream freezer are connected by detachable means to a power transmission shaft and a readily detachabl'e coupling member connects the shaft.

to the agitator, whereby rotary motion may be imparted to the movable elements of the ice cream freezer. The term washing mas chine, as employed in this specification, is

intended to include any clothes or dishwasher or centrifugal drier having a shaft extending up through the bottom and which is adapted to transmit motion to the apparatus as hereinafter described.

' Apparatus embodying features of our invention is illustrated in the accom anying drawings, forming a part of this app cation, wherein Fig. 1 is a vertical sectional view of a well known form of washing machine tub havin' our improved freezer attachment mounted therein, and shown in elevation;

'Fig. 2 is a vertical sectional view through the ice cream freezer;

Fig. 3 is a. lan view of the ice cream freezer, removed rom the washing machine;

Fig. 4 is a sectional plan view taken along the line IVIV of Fig. 2, and I Fig. 5 is a detail sectional view showing the power transmitting coupling between the power shaft and the cream receptacle.

Referring to the drawing for a better understanding of our invention, we show a tub 10 of a well known make of washing machine. Within the tub 10, and at the bottom thereof, is positioned an agitator 11, adapted to have imparted thereto, rotary motion in one direction or in alternately reversed directions, by means of a shaft 12, driven from any suitable power source. We have not shown the power means for driving the agitator 11, because it forms no part of our invention, and is well known in the art.

Our 1ce cream freezer comprises a cylindrical brine tank 13, a cylindrical cream receptacle 14, enclosed by the brine receptacle and concentric therewith, a lid 16 for the cream receptacle 14, and a dasher 17 within the cream receptacle 14. The brine tank 13 is surrounded by a cylindrical jacket 18 forming an annular chamber and which. communicates with the tank 13 through a port 19 provided in the brine tank 13 so that, as the ice in the brine tank melts and more ice is added, the water may pass through the port 19 and into the annular space defined by the jacket 18. This pre- 9 vents spilling of the brine into the tube which might tend to discolor it. The upper end of the jacket 18 is turned over at 21 to form a reinforced edgeand is secured to the brine tank 13 by a plurality of angle lugs 25 leavin the to open for the greater part so thgt the ovsrflow water may be emptied; The brine tank 13 is rolled over -at'the top, as shown at 22, in order to form a strengthened portion for supporting the tank and has pivotall portih ig straps 23. Each of the supporting straps 23 is provided, at its outer end, with screw clamp means 24, which are adapted to engage the upper flange 26 of the wash tub 10 and this form a supporting means for the brine tank 13.

' The cream receptacle 14 has extending through its bottom and secured thereto, in

15 any well-known manner to make it leak propf,

a member provided on its upper sidewith a depression 27 into which the lower end of the dasher stem 28 rests. The lower side of the member 30 is provided with a square 0 socket 29 adaptedto receive a squared head 31 of a coupling member 32. The lower end of the brine tank 13 is provided with a packing member 33 through which the coupling member 32 extends. Extending across the upper end 36 provided with a squared hole 37 adapted to receive the squared upper end 38 of the dasher 28. I.

The packing member 33 is provlded with a ground beveled seat 43, where it opens into the brine tank 13, the bevel seat cooperating with a complementary valve portion 44 provided on the coupling member." The coupling member 32 therefore serves to transmit power to the cream receptacle 14 and also acts. as

"a valve to prevent leakage of brine into the tub of the washing machine. In addition to the valve and seat provided, a suitablepacking nut 46 fits over the lower end ofthe packing member 33 so that the coupling member 32 may be further guarded against leak- Power is transmitted from the agitator 11 through a shaft 41, provided at its lower end with a slot 42 which is adapted to fit over the agitator 11. Fitting over the upper end of the shaft 41 is a hollow member 47 which bears against the packing nut 46. The coupling member 32 enters the upper end of the hollow member 47 and has secured to its lower end a cup-like member 48. A spring 49 surrounds the coupling member and bears, at its lower end, against the cup-like member 48 and at its upper end against the upper end of the hollow member 47. The spring 49 thusacts to hold the valve portion '44 of the coupling member 32 tightly on its seat, thus insuring that there shall be no leakage past the coupling member.

From the foregoing description, the operation of apparatus made in accordance with our invention will be apparent. Whenever it is desired to utilize ourattachment, 1t is mounted in the tub of the washing machine with the coupling 41 fitting over the agiconnected thereto a plurality of supof the brine tank 13 is a memberv tator- 11 and with the straps 23 clamped to the flange 26 of the tub by means of the screw clamps 24 so as to sus end the brine tank 13 concentrically with t e tube 10. The ice cream freezer is packed in the usual manner and the power means is put-in operation to impart rotary motion in alternately reversed directions to the agitator 11,, such motion being continued until the cream is frozen. The cream receptacle 14 may then be removed from the brine tank 13, and the brine tank 13 may then be detached and emptied, together with the receptacle 18.

From the foregoing it will be apparent that we'have devised an improved ice cream freezing attachment for a washing machine which is simple of design and easy of'manufacture and which embodies novel supporting and power transmission means.

While we have shown our invention in but one form, it will be obvious to those skilled in the art that it is not so limited, but is susceptible of various changes and modifications, without departing from the spirit thereof, and we desire, therefore, that only such limitations shall be placed thereupon as are imposed by the prior art oras are specifically set forth in the appended claims.
